厳しく

§ Understanding 厳しく (kibishiku)

The Japanese adverb 厳しく (kibishiku) means 'strictly,' 'severely,' or 'harshly.' It comes from the i-adjective 厳しい (kibishii), which means 'strict,' 'severe,' or 'harsh.' When you change an i-adjective to its adverbial form, you replace the final い (i) with く (ku). This is a common pattern in Japanese grammar.

§ How to use it in a sentence

厳しく (kibishiku) modifies verbs, describing *how* an action is performed. It tells you the manner or degree of the action.

§ Modifying verbs:

This is the most common use. 厳しく (kibishiku) will typically precede the verb it modifies.

Translation hint

The teacher guides the students strictly.

Translation hint

He is strict with himself and practices every day.

In the second example, 'strict with himself' is a natural English translation. In Japanese, '自分に厳しく' literally means 'strictly to himself' or 'severely to himself', modifying the implicit verb like 'applies himself' or 'treats himself'.

§ Common verbs used with 厳しく (kibishiku):

• 指導する (shidou suru): to guide, instruct
• 叱る (shikaru): to scold
• 罰する (bassuru): to punish
• 審査する (shinsa suru): to examine, review
• 問う (tou): to question, inquire
• 要求する (youkyuu suru): to demand, request
• 評価する (hyouka suru): to evaluate, assess

§ Expressing a 'harsh' or 'severe' situation (often with なる/する):

厳しく (kibishiku) can also describe a situation becoming harsh or severe, often used with 'なる' (naru - to become) or 'する' (suru - to do/make).

Translation hint

When winter comes, the cold becomes severe.

Translation hint

He deals with environmental protection strictly / harshly.

In these cases, 厳しく (kibishiku) often describes the intensity or difficulty of a situation or the strictness of an approach. There are no specific prepositions that 厳しく (kibishiku) uses, as it directly modifies the verb. The particle に (ni) in '自分に厳しく' or '環境保護に厳しく' indicates the indirect object or target of the strictness/severity, but it's not a preposition used *by* the adverb itself.

§ Not understanding the nuance of 'strictness'

The word 厳しく (kibishiku) can mean 'strictly,' 'severely,' or 'harshly.' The biggest mistake learners make is using it too broadly without considering the specific nuance. In English, 'strict' can apply to rules, people, or situations in many contexts. In Japanese, 厳しく often carries a stronger sense of severity or difficulty than just 'strictness' in a neutral rule-following sense.

English Hint

The teacher teaches students strictly/rigorously.

Here, 'strictly' implies a demanding and thorough teaching style, which fits the 'harshly' or 'rigorously' nuance of 厳しく.

§ Confusing it with 'precisely' or 'accurately'

Sometimes learners try to use 厳しく when they mean 'precisely' or 'accurately.' While a strict process might lead to precision, 厳しく itself doesn't carry that meaning. If you want to say something is done 'precisely,' you'd use words like 正確に (seikaku ni) or きっちり (kicchiri).

English Hint

This machine operates precisely.

Using 厳しく here would be incorrect, as the machine isn't operating 'harshly' or 'severely,' but rather 'accurately.'

§ Overusing it in casual settings

While 厳しく is a common word, it's generally used when describing situations or people that involve a certain level of demand, discipline, or difficulty. Using it in contexts where English might use 'strictly' for simple adherence to rules can sound unnatural. For example, if you just mean 'you must follow the rules,' using something like 規則に従う (kisoku ni shitagau - follow the rules) or 規則を守る (kisoku o mamoru - obey the rules) might be more appropriate than adding 厳しく unless the rules are particularly stringent or difficult to follow.

English Hint

Punctuality is strictly observed/required.

Here, 厳守 (genshu - strict observance/adherence) already contains the 'strict' meaning, making an additional 厳しく redundant or sometimes unnatural, depending on the context.

§ Not recognizing its usage with weather or conditions

厳しく is also frequently used to describe severe conditions, especially weather. Learners might overlook this usage, thinking it only applies to people or rules. For instance, a 'harsh winter' or 'severe market conditions' are common applications.

• 冬は厳しくなった。(Fuyu wa kibishiku natta.)

  English Hint

  The winter became severe/harsh.

• 市場の状況は厳しくなっている。(Shijō no jōkyō wa kibishiku natte iru.)

  English Hint

  Market conditions are becoming severe/tough.

In these cases, 'strictly' in English doesn't quite fit. The meaning leans more towards 'severe,' 'harsh,' or 'tough.'
